has been cropped.

* Updated TODO list

* modules/stream_out/transcode.c: when overlaying subtitles, duplicate frames if they are referenced by the decoder.

* video_chroma/i420_rgb.c: disable RV24 support (which was assuming 32 bits per pixels).

  (but *very* unlikely) segfaults

* stream_out/transcode.c: deinterlacing works again.

* modules/audio_filter/converter/dtstofloat32.c: added implementation for the new audio filter architecture.
* codec/dts.c: bug fix.
* codec/araw.c: added more PCM formats to the encoder.

* modules/audio_filter/converter/a52tofloat32.c: added implementation for the new audio filter architecture.

* modules/stream_out/transcode.c: respect input requested by encoder.

  + correct cropping of the decoded video when specified.
* stream_out/transcode.c: make sure the size of the encoded video is at least a multiple of 2.

* modules/demux/ogg.c, modules/demux/mkv.cpp:
  - store the vorbis/theora/speex headers in fmt.p_extra.
  - this change simplifies the code quite a bit and is a lot cleaner.
* modules/codec/vorbis.c, theora.c, speex.c, flac.c:
  - get the headers from fmt_in.p_extra or from the bitstream if empty.
* modules/mux/ogg.c:
  - recontstruct the headers from fmt.p_extra.

    + Removed unused menu files.
  * debian/rules:
    + Build libavformat.
  * include/vlc_common.h:
    + PACKAGE overrides PACKAGE_NAME.

* modules/mux/asf.c: bring the tracks back to a 0 based offset.

    + Disabled the GNOME, Qt, GTK+ and KDE interfaces in favour of the
      WxWidgets one.

    + Use PACKAGE_NAME instead of PACKAGE.
  * modules/codec/ffmpeg/ffmpeg.c:
    + This module does not require AltiVec for now.

  - Re-use our audio decoder modules instead of using libavcodec directly.
  - No more dependance on libavcodec.
  (downmixing is currently broken + you have to force the ffmpeg codec for a52)
* modules/audio_filter/format.c:
  - PCM audio format conversion filter using the new common filter architecture.
* modules/audio_filter/converter/mpgatofixed32.c:
  - implements both the old and new filter architecture (ie. useable in the transcoder).
* modules/codec/ffmpeg/audio.c:
  - fixes and cleanup.
